[clabasky]

hello Sencha friends!

I have a map on my app that shows a route between two locations. The issue is that the map shows mountain view, ca for about a second before loading my custom map Any advice would be awesome~!!!

 var myMask = new Ext.LoadMask(Ext.getBody(), {msg:"Loading..."});
myMask.show();
                    postcard.setActiveItem(mappanel);
		    
              //grab location from record       
                       var getaddress = postdetailcard.data.address;
                       var getzipcode = postdetailcard.data.zipcode;
                       var getcity    = postdetailcard.data.city;
                           
                         
              //geocode address            
                 var address = getaddress +', '+ getcity+', '+ getzipcode;             
                 var geocoder = new google.maps.Geocoder();
                		 
geocoder.geocode({'address': address}, function(results, status){
   if (status == google.maps.GeocoderStatus.OK) {


   		    var coord = results[0].geometry.location;	    
		    var directionsDisplay;
		    var directionsService = new google.maps.DirectionsService();
		    var map;


    directionsDisplay = new google.maps.DirectionsRenderer();  
                                                    
  var lat = locationstore.data.items[0].data.latitude;
  var lng = locationstore.data.items[0].data.longitude;
  
  var start = lat+','+lng;
  var end = coord;
  
  var request = {
    origin:start,
    destination:end,
    travelMode: google.maps.TravelMode.DRIVING
  };
  
  directionsService.route(request, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(result);
      
       
    var image = 'logo-map-sm.png';
              
		  //show marker     
			var marker = new google.maps.Marker({
			   map: map,
			    position: coord,
			    icon: image
			 });
			
			    var myOptions ={
			  zoom: 14,
			  center: coord,
			  mapTypeId: google.maps.MapTypeId.ROADMAP      
		       }
	    
			
			   //creates map
    var map = new google.maps.Map(document.getElementById("detailmap"), myOptions);
  directionsDisplay.setMap(map);
    }
  });
 
		      
       myMask.hide();                       				   		    
		    }
			  else {
			       alert("Geocode fail" + status);
			       myMask.hide();
			    }
                 });
